| This page is an alphabetical photo gallery of minerals from the Johnson Rd., Bow, New Hampshire locality. (A locality specific photo set from mindatnh.org) 27 species, 74 mineral photos The Johnson Road locality is a blasted ledge construction site containing a quartz crystal vein with sulfide ore mineralization. On some maps Johnson Road is labeled as River Rd. A majority of the specimens here were collected by collectors desiring to remain anonymous. This site is on private, commercial, property. A May 2018 permission request to collect minerals was denied. A very large warehouse is now (9/18) under construction on this site. The rear of this building is in the area where the ore vein minerals were collected. | |

Species: ANGLESITE ? Locality: Johnson Rd., Bow, NH Specimen Size: Approx. 0.1 mm anglesite crystal Field Collected: 2016 Catalog No.: u2110 Notes: |
 |
Species: ANGLESITE Locality: Johnson Rd., Bow, NH Specimen Size: 0.7 mm clear, rhombic prism, anglesite crystal Field Collected: 2016 Catalog No.: u2145 Notes: Backside reflections through this clear crystal make it appear hexagonal in this photo. Although both anglesite and cerussite are orthorhombic, these anglesite crystals lack the striations on the prism faces. Stack of 40 images with Nikon Plan 10 objective and Canon G9 camera |
 |
Species: ANGLESITE Locality: Johnson Rd., Bow, NH Specimen Size: 0.7 mm milky, rhombic prism, anglesite crystal Field Collected: 2016 Catalog No.: u2147 Notes: Flat rhombic prism termination is on top. Stack of 8 images with Meiji triocular scope objective and Canon G9 camera. Compare with photo taken with Nikon Plan 10 objective lens. |

Species: ANGLESITE Locality: Johnson Rd., Bow, NH Specimen Size: 1.5 mm anglesite crystal on 8 mm corroded galena crystal. Field Collected: 2016 Catalog No.: u2154 Notes: Stack of 57 images with Nikon Plan 10 objective and Canon G9 camera |
 |
Species: ANGLESITE Locality: Johnson Rd., Bow, NH Specimen Size: 0.4 mm rhombic prism Field Collected: 2016 Catalog No.: u2133 Notes: Stack of 34 images with Nikon Plan 10 objective and Canon G9 camera. Unsure if termination is natural or broken. There is some preferential iron staining on the front prism corner. |

Species: ANGLESITE Locality: Johnson Rd., Bow, NH Specimen Size: 1.8 mm anglesite broken cross-section rhombic prism with distinct color zoning. Field Collected: 2016 Catalog No.: u2133 Notes: A polished crystal section grain from this specimen was analyzed by EDS. This EDS analyses (BC271 - set 19) indicated a lead mineral, but unfortunately the Pb and S spectral lines substantially overlap, so one cannot determine from the analysis if sulfur is present or not. If sulfur is present, then the species indicated by the EDS analysis is anglesite, PbSO4. If sulfur is not present, then the species is cerussite, PbCO3. (there is a small carbon peak at the low spectral end, part of which may be due to the presence of carbonate ions and part due to the known presence of the sample carbon coating.) However a wet chemical test strongly suggests that this is anglesite. A drop of muriatic acid on a similar partial crystal on the specimen underside gave no carbonate fizz, (indicative of cerussite, a carbonate mineral). A similar test on a known cerussite specimen gave a good carbonate fizz, validating this cerussite characteristic. |
 |
Species: ARAGONITE Locality: Johnson Rd., Bow, NH Specimen Size: 2 mm field of view Field Collected: Tom Mortimer Catalog No.: u2197 Notes: Gives vigorous fizz in muriatic acid. Pale green fluorescence SW UV. |

 |
Species: BARITE Locality: Johnson Rd., Bow, NH Specimen Size: 1.2 mm co-joined pair of tabular barite crystals Field Collected: 2016 Catalog No.: u2110 Notes: I only found one specimen example of barite in a couple dozen pounds of Bow sulfide-quartz vein material that I broke down. I found it in one of the first chunks I broke apart. I expected to find more, but never did. A tiny anglesite crystal is at the top apex of the larger tabular barite crystal. |
  |
Species: BARITE ? Locality: Johnson Rd., Bow, NH Specimen Size: 1.2 mm cluster of barite crystals - see notes Field Collected: 2016 Catalog No.: u2110 Notes: One of these crystals has a distinct hexagonal tabular habit that is characteristic of the lead carbonate-sulfate, leadhillite. This crystal is outlined in the second photo. Other crystals in the cluster have more of a tabular-prismatic barite habit. |
   |
Species: CALCITE Locality: Johnson Rd., Bow, NH Specimen Size: 12 mm field of view - top photo. 0.5 mm calcite crystals oriented on dolomite rhombs. Field Collected: 2016 Catalog No.: 2071 Notes: These oriented calcite rhombs are quite interesting. My larger field views are not particularly satisfying. The largest FOV with this set was using +7 diopters on my Canon. The middle FOV was through the Meiji (stack of 23). The close-up was with the Nikon objective, stack of 18 images. Of the dozen or so multi-inch samples acquired from Paul Young, only one had calcite crystals. |
 |

 |
Species: CERUSSITE Locality: Johnson Rd., Bow, NH Specimen Size: 1 mm cerussite "V" twin Field Collected: 2016 Catalog No.: u2082 Notes: |
 |
Species: CERUSSITE Locality: Johnson Rd., Bow, NH Specimen Size: Pair of oxide coated, 0.8 mm, cerussite crystals Field Collected: 2016 Catalog No.: u2137 Notes: Several cerussite habits are present at this Bow locality, including this steep termination variety.

 |
Species: CERUSSITE Locality: Johnson Rd., Bow, NH Specimen Size: 1.2 mm cerussite crystal (largest) Field Collected: 2016 Catalog No.: u2156 Notes: This prismatic cerussite form is the most common at the Bow locality. Stack of 51 images with Canon G9 camera and Nikon Plan 10 objective. |
 |
Species: CERUSSITE Locality: Johnson Rd., Bow, NH Specimen Size: 1 mm cerussite crystal Field Collected: A Bob Wilken specimen and photo Catalog No.: u2156 Notes: |
 |
Species: CERUSSITE Locality: Johnson Rd. construction site, Bow, NH Specimen Size: Largest crystal is 1.0 mm Field Collected: Paul Young - 2016. Catalog No.: u2302 Notes: |
 |
Species: CERUSSITE Locality: Johnson Rd. construction site, Bow, NH Specimen Size: 0.5 mm bipyramidal cerussite crystal Field Collected: Paul Young - 2016. Catalog No.: u2303 Notes: Cerrusite at the Bow locality has many different habits, including the hexagonal bipyramid shown here. Prismatic crystals are the most common. |
 |
Species: CHALCANTHITE ? Locality: Johnson Rd., Bow, NH Specimen Size: 4 mm field of view Field Collected: 2016 Catalog No.: u2083 Notes: Overall 1.4 cm specimen has some sphalerite and hydrozincite. Wet tests: A tiny second zone on the matrix did not dissolve or appear to alter when a drop of water was added. Chalcanthite is water soluable. When a drop of muriatic was added, the mineral disolved. No fizz was observed (under my scope), but the area was very small. No colored residue was seen after the muriatic evaporated. |
 |
Species: CHALCOPYRITE Locality: Johnson Rd., Bow, NH Specimen Size: 10 mm field of view Field Collected: 2016 Catalog No.: u2155 Notes: At the Bow locality, chalcopyrite is rarely seen in vugs and when observed is almost always badly erroded. Green copper minerals are usually present with and on these relict crystals, as seen here. Chalcopyrite fully enclosed in quartz does retain its brassy color. |
 |
Species: COVELLITE ? Locality: Johnson Rd., Bow, NH Specimen Size: 5 mm field of view. This is sample analyzed. Field Collected: 2016 Catalog No.: u2152 Notes: A carbon tape EDS analysis (BC250) showed a copper sulfur zinc mineral with moderate oxygen. The Cu:S:Zn APFU ratio from the analysis was 9:3:1. The Cu:S ratio for covellite (CuS) is 1:1. It is uncertain if the zinc is essential for this mineral sample or not. There are 12 species with only Cu and S as essential, with varying ratios of Cu and S. There are no minerals with Zn, S and Cu essential, but no oxygen. If the oxygen is essential, then the number of candidates is six, but none of these visually fit. |
 |
Species: COVELLITE Locality: Johnson Rd., Bow, NH Specimen Size: 2.5 mm field of view Field Collected: 2016 Catalog No.: u2160 Notes: Covellite filled cavity in quartz. |
  |
Species: COVELLITE Locality: Johnson Rd. construction site, Bow, NH Specimen Size: 6 mm field of view, top photo. 12 mm field of view lower photo. Field Collected: Paul Young - 2016. Catalog No.: u2302 Notes: Blue covellite inside cavity outlined by earlier generation crystal. Interesting. |
 |
Species: COVELLITE Locality: Johnson Rd. Locale, Bow, NH Specimen Size: 0.8 mm field of view Field Collected: Paul Young - 2016 Catalog No.: Bob Wilken specimen and photo Notes: Similar to a previously analyzed Cu,S,Zn Johnson Rd. specimen that suggested covellite as a "best fit", but not particularly well. |
 |
Species: DENDRITE Locality: Johnson Rd., Bow, NH Specimen Size: 6 mm field of view. Quartz crystal with Mn dendrites Field Collected: Jim Cahoon Catalog No.: u2195 Notes: |
 |
Species: DOLOMITE Locality: Johnson Rd., Bow, NH Specimen Size: 1.5 cm field of view Field Collected: 2016 Catalog No.: 2070 Notes: A few tiny calcite crystals are sprinkled on the curved, rhombic, dolomite crystals. This could be ankerite, but recent studies have shown that most "ankerite" is ferroan dolomite. |
 |
Species: GALENA Locality: Johnson Rd., Bow, NH Specimen Size: 9 cm specimen. Galena in milky quartz. Field Collected: 2016 Catalog No.: NC Notes: Yellow arrows point to areas of secondary minerals. Galena is the most common sulfide mineral at the Johnson Rd. locality. |
 |
Species: GALENA Locality: Johnson Rd., Bow, NH Specimen Size: 5 cm specimen. Galena in milky quartz. Field Collected: 2016 Catalog No.: 2073 Notes: |
 |
Species: GALENA Locality: Johnson Rd., Bow, NH Specimen Size: 10 mm field of view. Galena crystal in quartz crystal vug. Field Collected: Jim Cahoon Catalog No.: NC Notes: No image stacking. This is the only euhedral galena crystal I saw from this Bow locality. |
 |
Species: GALENA Locality: Johnson Rd. construction site, Bow, NH Specimen Size: 4.5 cm specimen with 3 cm partial galena crystal. Field Collected: Paul Young - 2016. Catalog No.: NC Notes: Illustrates size of embedded galena crystals at the Bow locality. |
 |
Species: GOETHITE Locality: Johnson Rd., Bow, NH Specimen Size: 2.5 cm specimen. Field Collected: 2016 Catalog No.: u2165 Notes: A January, 2018 carbon tape EDS analysis showed mostly an iron oxide (goethite) with a bit of zinc and sulfur. I had considered this deep orange mineral might be minium, the lead-oxide mineral, due to all the decomposing galena nearby. |
 |
Species: GREENOCKITE on sphalerite Locality: Johnson Rd., Bow, NH Specimen Size: 2 mm field of view Field Collected: 2016 Catalog No.: u2200 Notes: |
 |
Species: GYPSUM Locality: Johnson Rd., Bow, NH Specimen Size: 5 mm field of view Field Collected: 2016 Catalog No.: u2164 Notes: A visual identification. Mineral is fluorescent pale white in SW UV. EDS verification planned. A 16 image stack via Meiji trinocular port. |
 |
Species: GYPSUM Locality: Johnson Rd., Bow, NH Specimen Size: 0.7 mm crystal group Field Collected: 2016 Catalog No.: A Bob Wilken specimen and photo Notes: A visual identification.. |
   |
Species: GYPSUM Locality: Johnson Rd., Bow, NH Specimen Size: 1 mm field of view. Second, zoomed view, 0.7 mm FOV. Third photo shows overall 2.7 cm specimen. Field Collected: 2016 Catalog No.: u2131 Notes: A visual identification. Mineral is fluorescent pale white to slightly yellow-greenish in SW UV. Gypsum is frequently fluorescent. Initial thought was that this is hydrozincite, but fluorescence is too weak for that species. Bob Wilken suggested aragonite, but a small removed grain gave no muriatic acid fizz. EDS verification planned. A 47 image stack with Nikon Plan 10 objective. Third photo shows overall specimen with gypsum coating quartz crystals to the right of a galena mass. |
 |
Species: HEMIMORPHITE Locality: Johnson Rd. Locality, Bow, NH Specimen Size: 1.3 mm field of view Field Collected: Paul Young - 2020 Catalog No.: u2586 Notes: |
 |
Species: HEMIMORPHITE Locality: Johnson Rd. Locality, Bow, NH Specimen Size: 4 mm field of view Field Collected: Paul Young - 2020 Catalog No.: u2587 Notes: |
  |
Species: HEMIMORPHITE Locality: Johnson Rd., Bow, NH Specimen Size: 0.1 mm hemimorphite cluster on oxide coated quartz crystal, with second zoomed view Field Collected: 2016 Catalog No.: u2134 Notes:[tm] This is only the second occurrence I have seen of New Hampshire hemimorphite. EDS verification would be reassuring. There is another Pb mineral with a similar morphology, dundasite, PbAl2(CO3)2(OH)4 · H2O Hemimorphite chemistry is: Zn4Si2O7(OH)2 · H2O , so EDS differentiation should be straightforward. |
 |
Species: HEMIMORPHITE Locality: Johnson Rd., Bow, NH Specimen Size: 0.7 mm hemimorphite cluster on quartz crystal Field Collected: 2016 Catalog No.: u2140 Notes: Hemimorphite is a very late stage mineral at this Bow locality. It is found on oxide coated quartz crystals and in and on masses of goethite. The habit is typical for hemimorphite: clusters of lustrous, fan-like, sprays. Individual crystals rarely exceed one-half mm. |
 |
Species: HEMIMORPHITE Locality: Johnson Rd., Bow, NH Specimen Size: 1.2 mm hemimorphite Field Collected: 2016 Catalog No.: u2203 Notes: |

Species: HEMIMORPHITE Locality: Johnson Rd., Bow, NH Specimen Size: 1.2 mm hemisphere of crystals. SW UV image below Field Collected: Tom Mortimer Catalog No.: u2182 - Gifted to Fred Davis Notes: From a 50 image stack with Nikon objective. I had no idea what this was. My best quess was smithsonite. When I forwarded the photo to Peter Cristofono, he suggested I check it with UV. I did this and observed the intense green fluorescence. When Peter saw this, he opined that this was very likely willemite, Zn2SO4. Peter stated that the only other reported New England occurrence was from the Copper Valley Mine in New Haven, CT. (The mindat.org photo of this shows a "Massive [10 mm] aggregate of tiny, white willemite crystals". The Bow specimens are excellent in comparison. Based on his sulfide ore vein collecting in the southwest, Bob Wilken also independently suggested a willemite ID. I shared Bow samples from my limited supply with several MMNE members at the symposium. Fred Davis, with occasional access to a Raman spectroscopy instrument, was able to provide an analysis. The Raman analysis gave a very good match for hemimorphite. In the email that accompanied the plot, Fred stated: “saw the bright fluorescence. Got it in the Raman and [was] shocked - hemimorphite. Probed all over the fragment, 6 or 7 different locations - the results were very consistent. I really wanted it to be willemite”. A June 2018 EDS analysis (BC291) of similar u2178 indicated a simple zinc silicate, consistent with hemimorphite. |

Species: UNDETERMINED Cu, Pb, S mineral Locality: Johnson Rd., Bow, NH Confidence: 2 Chemistry: [ ]2W2O6(H2O) Specimen Size: 1.5 mm field of view Field Collected: 2016 Catalog No.: A Bob Wilken specimen and photo Notes: [bw] "These are definitely cubes with a mirror-like luster. There's no way they can be anglesite. A possibility that I've been wondering about is galena. It doesn't usually form individual, separate cubes that I've seen. But, maybe it could if it were to condense from hot gases. On the other hand, these little cubes are usually in vugs where other sulfides seem to have deteriorated. And, often there is a bluish covellite-look to the crusty coating surrounding them. It's what again makes me think the Pb has recombined with Cu to form murdochite." An Octobr, 2018 carbon tape grain EDS analyses showed only tungston and oxygen, suggesting hydrokenoelsmoreite, [ ]2W2O6(H2O), as a possible species. Two follow-on Carbon tape EDS analyses ( EDS analyses BC495a and EDS analyses BC495c) indicated a Cu, Pb, S mineral, more consistent with other species found at the Johnson Rd. locality. Presently, there are no IMA approved species that fit this chemistry. These cubes may be a mineral mixture or a partial pseudomorph. |
 |
Species: UNDETERMINED Cu, Pb, S mineral Locality: Johnson Rd. Locale, Bow, NH Specimen Size: 1.3 mm field of view Field Collected: Paul Young - 2016 Catalog No.: Bob Wilken specimen and photo Notes: First analysis attempt did not probe the correct grain spot. |
 |
Species: UNDETERMINED Cu, Pb, S mineral Locality: Johnson Rd., Bow, NH Specimen Size: 1.2 mm field of view Field Collected: 2016 Catalog No.: u2212 Notes: Stack of 15 images in 0.01 increments with Nikon Plan 10 objective and Canon G9 camera. These are not as lustrous as those in Bob Wilken's photo. Galena is also present on this micro-boxed specimen. |
  |
Species: UNDETERMINED Cu, Pb, S mineral Locality: Johnson Rd., Bow, NH Specimen Size: 1.1 mm field of view Field Collected: 2016 Catalog No.: u2213 Notes: Oriented for cube face reflection. Helicon Focus stacking software method C (top) and method A (lower) on same image stack. |
 |
Species: HYDROPLUMBITE ? Locality: Johnson Rd., Bow, NH Specimen Size: 9 mm field of view. Field Collected: 2016 Catalog No.: u2136 Notes: Perhaps hydroplumbite, a hydrated lead oxide, the only Pb oxide that is white. This powdery white unknown has shown up on several specimens. It appears to be an weathering product of galena. This small chunk is solid galena, except for this powdery crust. I cannot find any photos of hydroplumbite. Mindat has it as "Approved, grandfathered, questionable." It is not listed in my 2008 Fleisher's. Tests: Not fluorescent. Not soluble in water or muriatic acid. A carbon tape grain EDS analyses (BC286 - set 19) indicated a lead mineral with oxygen. Unfortunately, the EDS did not resolve an ambiguity of lead and sulfur, so the possibility of powdered anglesite cannot be eliminated. The tiny bit of aluminum in the plot is likely a contaminant. |
 |
Species: HYDROZINCITE Locality: Johnson Rd., Bow, NH Specimen Size: 2.5 mm field of view Field Collected: 2016 Catalog No.: u2083 Notes: A visual identification. Mineral is fluorescent bright white in SW UV. The dark mineral directly above the hydrozincite is sphalerite, the likely parent mineral of the hydrozincite. |
   |
Species: HYDROZINCITE Locality: Johnson Rd. Locality, Bow, NH Specimen Size: 13 mm field of view and 3.5 mm field of views, (daylight and SWUV) Field Collected: Paul Young Catalog No.: u2585 Notes: Hydrozincite is fluorescent blue-white. Nice balls, such as these are, less common than simple coatings. |
 |
Species: LINARITE Locality: Johnson Rd., Bow, NH Specimen Size: 2.0 mm field of view Field Collected: 2016 Catalog No.: u2151 Notes: A visual identification. I made three image stack attempts to capture this tiny cluster. This was the best. A few other embedded blebs of linarite were spotted in the Bow material I reviewed, but this was the only group of distinct crystals. |
 |
Species: MALACHITE Locality: Johnson Rd., Bow, NH Specimen Size: 5 mm field of view Field Collected: 2016 Catalog No.: u2144 Notes: A tiny grain from this specimen was pushed into a drop of muriatic acid under my scope and dissolved with bubbles, proving a carbonate. |
 |
Species: MALACHITE Locality: Johnson Rd. construction site, Bow, NH Specimen Size: 0.4 mm high malachite spray Field Collected: Paul Young - 2016. Catalog No.: u2303 Notes: This is the only euhedral malachite spray I have seen from the Bow locality. |
 |
Species: OPAL var. Hyalite Locality: Johnson Rd. construction site, Bow, NH Specimen Size: 10 mm field of view Field Collected: Paul Young - 2016. Catalog No.: u2304 Notes: This opal is not fluorescent.A smithsonite ID was considered, but no fizz in muriatic acid that would indacate a carbonate mineral such as smithsonite. |
 |
Species: PYRITE Locality: Johnson Rd., Bow, NH Specimen Size: 0.2 mm pyrite crystal Field Collected: 2016 Catalog No.: u2083 Notes: Pyrite crystals, even tiny ones, are uncommon at this Bow locality, at least in the material I have reviewed. |
 |
Species: PYROMORPHITE coating Locality: Johnson Rd., Bow, NH Specimen Size: 5 mm field of view Field Collected: Jim Cahoon Catalog No.: A Bob Wilken specimen and photo Notes: An EDS analysis done by Kerry Day for Bob Wilken indicated this yellowish coating is pyromorphite. |
 |
Species: PYROMORPHITE Locality: Johnson Rd. construction site, Bow, NH Specimen Size: 4 mm field of view Field Collected: Paul Young - 2016. Catalog No.: u2300 Notes: Only a few specimens with micro pyromorphite showed up in the very last box of locality "rough" that Paul collected. Unfortunately, it is unlikely there will be any more. |
   |
Species: PYROMORPHITE Locality: Johnson Rd. construction site, Bow, NH Specimen Size: 5 mm field of view Field Collected: Paul Young - 2016. Catalog No.: TBC (& diamond saw trimmed to miniature size specimen) Notes: Second & third photos taken with Nikon Plan 10 objective, a stack of 14 images. The fine acicular sprays are perhaps aragonite. |

Species: QUARTZ Locality: Johnson Rd., Bow, NH Specimen Size: 7 cm specimen - cleaned in Iron Out Field Collected: Tom Mortimer Catalog No.: 2075 Notes: Iron Out cleaned quartz specimens frequently are less photogenic. |
 |
Species: QUARTZ Locality: Johnson Rd., Bow, NH Specimen Size: 1 cm field of view. Milky quartz crystals with green inclusions Field Collected: 2016 Catalog No.: 2072 Notes: The soft chalk-white mineral is likely kaolinite. It is not fluorescent. |
  |
Species: SMITHSONITE Locality: Johnson Rd., Bow, NH Specimen Size: Top view 2.2 mm FOV. Lower view 0.9 mm FOV Field Collected: 2016 Catalog No.: u2083 Notes: An EDS analysis on a tiny polished grain from this area gave an inconclusive result. The result suggested the balls may be an overgrowth-combination of several minerals, perhaps one being smithsonite. There is a moderate zinc content present. The sodium within the Zn plot peak may be due to a contamination of the carbon coating solvent. This small sample will not withstand another sample extraction without destroying it. A small zone of hydrozincite is present on this specimen. |
